[jira] [Resolved] (COUCHDB-1163) Document returned by id, but
cannot be found by rev
[ https://issues.apache.org/jira/browse/COUCHDB-1163?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Robert Newson resolved COUCHDB-1163.
------------------------------------
Resolution: Fixed
Documents affected by COUCHDB-885 (where important rev information was not replicated) can have errors in their rev tree. The patch for this ticket corrects those errors when the document is subsequently updated or compacted.

> Somehow, our cluster has developed the following problem on a handful of documents. Will post reproduction steps if we find them. All properties have been redacted. All the documents this affects also have attachments, if that is significant. Once a document is in this situation, it causes conflict detection, replication and include_docs to behave incorrectly or outright fail.
